Patent CA-2152217-A1 (CA)
Title: Compact centrifugal fan
Inventor: SMILEY WILLIAM A III
IPC: F04D29/42
Filed: 1995-06-20
Abstract: A centrifugal fan includes a housing that defines an air inlet leading to an air chamber defined within the fan impeller and an air exit port coupled to an air passageway. The housing includes a shroud that defines a two zone air passageway in the housing. The first zone, commencing adjacent to the base of the exhaust port, is a conformal portion that is conformal to the exterior diameter of the centrifugal fan and spaced slightly apart therefrom.  The second zone of the shroud is a scroll portion wherein the angle of expansion is capable of expanding between 10° and 15°.  An air restrictor plate is supported inside the air chamber of the centrifugal fan.  At ` the greatest width of the air restrictor plate, the air restrictor plate subtends an arc that is substantially coextensive with the arc subtended by the first conformal zone of the shroud.  The restrictor prevents the flow of inlet air through the centrifugal fan in the region of the conformal shroud.

Title: Shoe-Cover
Inventor: SCHUERCH PRIMO
IPC: A43B23/06
Filed: 1995-08-31
Abstract: A shoe cover for being worn over the shoes consists of a cover foil adapted to protect the shoe and at least a part of the calf of a person and a reinforcing foil adapted to rein-force at least the sole portion of the cover foil. The cover foil is made of a first soft or plasticized polymer, and the reinforcing foil is made of a second soft or plasticized polymer. Besides the sole portion, the cover foil consists of a shaft portion. The sole portion of the cover foil is rein-forced by the reinforcing foil by welding them together by means of a plurality of punctual welding points. Those weld-ing points form a plurality of punctual recesses in the rein-forcing foil, which recesses cause a sucker effect, such that a high adhesion between the shoe cover and the ground re-sults. At the shaft portion, the cover foil is provided with a strap or a tape which allows to tighten the shoe cover at the foot or calf of a person. Such a shoe cover is light-weight, may be used several times and, due to the fact that it may be folded, needs not much space for storing.

Title: Device for propelling a curling rock
Inventor: WEISS DAVID
IPC: A63B67/14
Filed: 1995-12-21
Abstract: A propulsion device for use in propelling a curling rock comprises a head which engages a rock so as to apply a pushing action from an elongate handle so that the player can stand while pushing the handle and applying the propelling force. On the rock is mounted a tubular member carried on the handle of the rock which has a surface for engaging a pair of arms on the propulsion head so that the tubular member is aligned at right angles to the line of propulsion. A loose cable extends from the head to a fastener on the tubular member at one end of the tubular member with the amount of force applied by the fastener before release being variable. Thus, as the rock leaves the head after the propulsion stroke, the loose cable tightens and applies a rotation force on the tubular member and therefore the handle up to a predetermined rotation torque depending upon the selection of the fastener element. Thus the rock is propelled with a variable propulsion force and a variable rotation rate both of which are selectable by the player.

Inventor: MONCRIEF FRANK N
IPC: B65B61/20
Filed: 1995-06-12
Abstract: A method and apparatus (10) for inserting partitions (P) into a group of articles (A) is disclosed. The method includes combining articles, such as beverage containers, to form an article group (G) of predetermined configuration, including longitudinal rows of articles. The article group is conveyed toward a divider (11) disposed in the path of travel.

Title: Continuous in-situ combination process for upgrading heavy oil
Inventor: BRONS GLEN
IPC: C10G53/12
Filed: 1996-04-09
Abstract: The invention relates to an integrated, continuous process for the removal of organically bound sulfur (e.g., mercaptans, sulfides and thiophenes) comprising the steps of contacting a heavy oil, sodium hydroxide, hydrogen and water at a temperature of from about 380°C to 450°C to partially desulfurize the heavy oil and to form sodium sulfide, contacting said sodium sulfide with a transition metal in water to form a transition metal sulfide, sodium hydroxide and hydrogen. The sodium hydroxide is recirculated and the transition metal sulfide is removed. The partially desulfurized, dewatered heavy oil is treated with sodium metal under desulfurizing conditions, typically at a temperature of from about 340°C to about 450°C, under a hydrogen pressure of at least about 50 psi to essentially desulfurize the oil, and form sodium sulfide. Optionally, the sodium salt generated can be regenerated to sodium metal using regeneration technology. The process advantageously produces essentially sulfur-free product oils having reduced nitrogen, oxygen and metals contents and reduced viscosity, density, molecular weight and heavy ends.

Title: Local delivery of fibrinolysis enhancing agents
Inventor: DUNN RANDALL C
IPC: A61K35/12
Filed: 1994-12-09
Abstract: A method of preventing adhesions by topical administration of fibrinolysis enhancing agents is described. The method uses a topically applied polymeric matrix for delivery of a fibrinolytic agent, preferably urokinase, tPA, hirudin, or most preferably, ancrod. In the most preferred embodiment, the matrix is extremely thin and is polymerized in suti to form a biodegradable polymeric matrix. The matrix provides controlled release of the agent over a period of time effective to prevent surgical adhesions and is biodegradable, usually within the same time frame. Examples demonstrate that the combination of the matrix and the urokinase, tPA, birudin, or ancrod is effective in preventing surgical adhesions.

Abstract: In a sewing station, a preceding cloth piece is sewn to a slide fastener chain from a leading end of the preceding cloth piece to a predetermined posi-tion short of a trailing end thereof, and the sewing is terminated when it reaches the predetermined position. On the other hand, in a cloth-piece supply station, a succeeding  cloth piece is fed at a high speed toward the sewing station to an upstream position spaced a predetermined distance from the trailing end of the preceding cloth piece while being stopped, whereupon the sewing is started when the leading end of the succeeding cloth piece contacts with or nearly con-tacts with the trailing end of the preceding cloth piece.  As a result, the remaining  portion of the pre-ceding cloth piece is sewn.  These driving timing is sequentially controlled via a control unit based on various detection signals from a plurality of cloth-piece detectors.
